protected function Form::massageAllClasses in GridStack 8.2

Returns merged $[wrapper|row]_classes and $selected_classes.

We do this since we don't store massive class options, instead interpolated into the existing string [wrapper|row]_classes option during form validation to avoid similar logic at front-end.
